Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, wipers, security system, and HVAC controls.
Is this BCM ready to install right out of the box?
Yes. We pre-program the module to your vehicle’s VIN before shipping. This ensures it is ready for a simple plug-and-play installation with no additional dealership programming required.
